To all whomtt may concerm l State of Ohio, have invented new and usefullImprovements:in .Ventilating Spigot and Pump Gombined,of which thefollowing is-a ,description, reference being had to the accompanyingdrawings making a part of this speciication',`in which- Figure l'is an`outside view of the implement. Figs. 2, 3, 4.-, 5, and 6 are detachedsections. Fig. y7 isa transverse longitudinal section. y Like letters ofreference refer to like parts in the several views.

This invention is forventilating beer-barrels and other barrels, and forforcing air into the same, in order to cause the contents of the barrelto iiow, and to produce a pressure on the liquor while in thebarrel,without allowing the gas and flavor of the liquor to escape.

The peculiar construction and operation of the invention are,substantially, as follows: The lirst part of the device consists of atubular spigot, A, Figs. 1 and 7, having a conical end, having a head orchamber. B, in which is screwed a valve-seat, C, Fig. 7, a detached viewof which is shown in Fig. 4, whereof D is the valve, secured thereto bya set-screw, a.

v It will be observed that the seat ol' the valve is slightly concave.The valve consists of a thin disk of rubber, (or other appropriate ma-Through the valve-seat ber, which, however, may be more or less. Thesecond part of the invention consists of a pump, E, constructed asfollows: F is the cylinder ot' the pump; Gr, the piston, and 1 the rodor stein Working in a stuling-box, J,

' through which are made air-passages K, Fig.

7. To the end of the piston is secured a valve, L, Fig. 7, by means of aset-screw, o. Said valve consists of a thin disk of rubber or `otherequivalent material. The end of the pistou (the valve-seat) is slightlyconvex, at the center of which is a boss, d, as shown in Fig. 3. Throughthe piston are made air-- passages e, Fig. 7, also shown in thedetachedview, Fig. 3. Said boss and'air-passages are covered by the valve, asshown in Fig. 2.

The pump above described is attached .to

driven into thebarrcl. The valve D, while it prevents the outiiow of thebarrels contents by closing the Aairpassages b, will, when the pressureof the air on the outside of `the barrel is so great as to preventthe'iiow of the liquor, open and allow suliicient air to pass into thebarrel to cause the liquor to run out. Hence, on drawing-the liqnprthrough'thefaucet, a constant supply of air is admitted into the barrelthrough the spigot to lill` the vacuum above the liquor as'fast as itmay be formed by the constant drawingoff of the contents of the barrelwithout allowing any of the gases or the davor ofthe liquor te escape.

It is often found necessary on drawing off a portion of'a barrel of beerto have what is left remain under a strong pressure of air, to preventit from souring, which it will do if' allowed 'to remain without suchpressure for any considerable time. To produce this pressure on the beeris the purpose ot' the pump above described, and which is applied to thespigot, as shown in Fig. 7. Now, ondrawing back the pistou from itsposition shown in Fig. 7, no

vacuum will be formed between it and the spigot, as the air from theoutside will pass in through the air-passages K of the stuffing-box intothe cylinder, thence through the piston to the spigot; and if thepressure of the air on the valve D be strong enough, it will open thespigot-valve and rush into the barrel, whereas, if the air does not makeits way into the barrel, it can be forced in by the pump, the airopening the spigot-valve, and at the same time closing the valve L ofthepistou, so that the air cannot escape back through the piston.

By this means a strong pressure of air canl be exerted upon the contentsof the barrel. The pump, when not required for the purpose specified,may be detached from the spigot and e f l114.378

laid aside. rIhe spigotleft in -the barrel may be allowed to remaintherein permanently as necessary. It is notnecessary, however, to re-Imove the pump iu order 'that the spigot may actas a ventilator, as itwill act equally well for that purpose Whether thepump be attached to itor not. i

What I claim as my-inventiou, and desire to secure by Letters Patent,is-

1. In a veutlspigotand pump combued,the detachable spigot A, consistingvof a tubular y UWitnesses:

2. In combination With the tubular Ventilating-spigotA, the pumpE,lconsisting of the cylinder F, stuffing-'box' J, provided withairpassages K, piston G, havingHair-passagcs e,
